Spatial data on catchment characteristics

Attention: SwissTopo has recently changed its coordinate system (see here, migration to be finished by 2016). The resources below might use the old system (6 digits) or the new system (7 digits).

This page lists spatial data that is more or less static, for spatial meteo data, see dedicated page.

Swiss hydrological atlas:

Includes information on catchments (text, pdf-maps, shape files and raster data but no time series): see here.

To help Atlas navigation: remember that this was a printed book before. The information has been made available in pdfs (page copies), in xls sheets and shape files (see "download tab") and in a WebGIS. Any meta data is to be retrieved either from the map pdfs or from the explanation text that comes with the data downloads (in French: texte explicatif)

The hydrological atlas also contains a database of small subcatchments, as xls file or as shape file (here). These older delimitation comes with some hydrological catchment characteristics, e.g. the slope or the amount of impervious area (see explanation in the corresponding atlas page, pdf).

Soil use statistics (resolution 100x100m) from the Swiss Federal Office for Statistics, here (not sure what the distribution rules there are; for EPFL, refer to your responsible for data download from EPFL GEODATA).

Location illustrations: if you need a very quick-to-produce map to locate your work, you might want to use map.wanderland.ch where you can produce all kind of maps based on SwissTopo data (useful for non GIS users or if you do not have access to SwissTopo maps).
